on Complete Distribution System Materials Inventory Physical Verification Requirements
As Municipal Community Water Supplies, please refer to the additional information on the Complete Distribution System Materials Inventory (CDSMI) required by the lead and copper provisions of the Michigan Safe Drinking Water Act, 1976 PA 399, as amended (Act 399). Pursuant to Rule 325.11604 (c)(ii) of Act 399, a CDSMI must be submitted to the Michigan Department of Environment, Great Lakes, and Energy (EGLE) by January 1, 2025.
The purpose of the CDSMI is to characterize, record, and maintain a comprehensive inventory of distribution system materials, including service line materials on both public and private property. This should include the establishment or continuation of a comprehensive record management system that is updated regularly as inventory is added, changed, or confirmed. Please review the “CDSMI Overview” for more information.
The focus of this memo is to provide information regarding one step in the CDSMI process: the nature and scope of minimum service line physical verification expectations. This is NOT meant to serve as extensive and final guidance on all actions necessary to produce a CDSMI. Additional guidance will be provided in the future. This memo provides information about the minimum expectations for physical verification of service line materials to help systems planning for and conducting verification efforts. Planning for and physical verification of service line materials should be conducted in a timely fashion to enable compliance with the CDSMI submittal deadline of January 1, 2025.
Please refer to the “Minimum Service Line Material Verification Requirements” which describes minimum expectations for physical verification of service line materials. In summary:
- Physical verification of a randomly selected subset of service lines of “unknown” material will be required for most supplies. Note that “known” is defined conservatively in the enclosed guidance. The minimum number of service lines requiring physical verification is dependent on the water supply’s total number of “unknown” potable water service lines.
- A multi-segment physical verification is expected for each of the randomly selected service lines.
- A record of material and verification method must be maintained for each segment of each randomly selected service line.
- Results of physical verification should be compared with existing records to assess their accuracy.
- Based on results of the minimum physical verification, additional verification efforts may be required.
EGLE will be hosting two free webinars to review the requirements described in this document (both webinars cover the same content). Please consider attending one of these sessions:
